Given numbers are 421,918,261,310
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,918,261,310 is 1737218610.
Find LCM of 421,918,261,310 with Prime Factorization
| 2 | 421, 918, 261, 310 |
| 3 | 421, 459, 261, 155 |
| 3 | 421, 153, 87, 155 |
| 421, 51, 29, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 421 x 51 x 29 x 155 = 1737218610
Therefore, the lowest common multiple of 421,918,261,310 is 1737218610.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
421 x 918 x 261 x 310 = 31269934980
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
421 : 1, 421
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
261 : 1, 3, 9, 29, 87, 261
310 : 1, 2, 5, 10, 31, 62, 155, 310
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,918,261,310, is 1.
Now, the common factors can be found like this.
421:421
918:2x 3x 3x 3x 17
261:3x 3x 29
310:2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3 = 18
Therefore, the value for common factors is 18.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 31269934980/(1x18)
LCM = 31269934980/18
LCM = 1737218610
Thus, we can understand that the LCM of 421,918,261,310 is 1737218610.
